A MRT to Optimize a JITAI for Alcohol Craving and Suicide Ideation

November 2, 2026 updated by: Medical University of South Carolina

A Micro-Randomized Trial to Optimize a Just-in-Time Adaptive Intervention for Alcohol Craving and Suicide Ideation

This study will develop and evaluate a brief, personalized, single-session telehealth intervention combined with a four-week just-in-time adaptive intervention (JITAI) delivered via text messaging for adults with alcohol use disorder (AUD) and suicidal thoughts and behaviors. The study includes qualitative interviews, pilot testing, and a 28-day micro-randomized trial (MRT). In the MRT phase, participants (N=75) will be repeatedly randomized multiple times per day to receive text messages targeting craving and suicide ideation or to receive no message. Outcomes include alcohol craving, suicide ideation, alcohol consumption, and engagement with intervention strategies

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Sequential Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Single arm. Groups of people are not randomized. Each person is repeated randomized.

Groups of people are not randomized. Each person is repeated randomized 112 times over 28 days to text message vs no text message. Within the text message condition, there is additional randomization to text message choice and text message language conditions.

At four time points each day (112 time points across the 28-day study), each participant will be randomized to text message or no text message. Within the text message condition, there will be further randomization to Text Message Choice and Text Message Language conditions.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Integrated Plan Engagement
Time Frame: 28-day MRT period

Participants will complete the following yes/no EMA item four times a day: "Since the last survey, I completed a strategy from my Integrated Plan." This item, created by the study team for this study, will assess the completion of any intervention strategy from the patient's individualized Integrated Plan during the 28 day period.

28-day MRT period
Alcohol Craving
Time Frame: 28-day MRT period

Participants will complete the following EMA item (on a 0-10 Likert scale) four times a day: "Since the last survey, I thought about drinking or how good a drink would make me feel." This item, drawn from a well-established measure of alcohol craving (Penn Alcohol Craving Scale) will assess craving during the 28 day period.

28-day MRT period
Suicide Ideation
Time Frame: 28-day MRT period

Participants will complete the following EMA item (on a 0-10 Likert scale) four times a day: "Since the last survey, I thought about killing myself." This item, drawn from a well-established interview that has also been used as a self-report measure to assess varied self-injurious thoughts and behaviors (Self-Injurious Thoughts and Behaviors Interview-Revised) will assess thoughts of suicide during the 28 day period. This item has been used previously by the PI in EMA studies.
